VB Classic Comments

Commenting Code
VB Classic, like all the VB-based languages, uses a single quote (') or the original class-style basic "REM" (most developers just use a quote). VB Classic does NOT have a multiple line comment.

Directives - #

Directives are sometimes called compiler or preprocessor directives. A # is used for directives within VB Classic code. VB Classic offers only an #If..then/#ElseIf/#Else directive.

Multi-Line Comment Code Trick

You can simulate a multi-line comment with code which is useful especially if you wish to comment out a block of code.

For example:

If False Then

 '...code here skipped.

End If

Using Directives

Here is a simple example of using VB Classic's directive (change True to False to switch it).

#Const MyDirective = True
 

#If MyDirective Then
      MsgBox ("Yes")
#Else
      MsgBox ("No")
#End If
